Abstract

Possible application of a novel ionic liquid 3-methylpiridinium salicylate (3-MPS) in Liquid Scintillation Counting measurements has been explored. Its addition to several radionuclides' aqueous solutions shown a significant influence on 210Pb Cherenkov spectra, 210Pb and 226Ra gross alpha/beta spectra, even on 3H spectra appearance. 3-MPS manifested both wavelength shifting and scintillating effect, indicating that 3-MPS or other ionic liquids of similar structure soon might be implemented into the common LSC practise as an alternative to the commercial LSC cocktails.

Keywords: (210)Pb/(210)Bi detection; (3)H determination; Gross alpha/beta measurements; Ionic liquids; Liquid scintillation counting; Quantulus 1220.
